AS-i安全监控器概述(上)

Summarization of AS-interface Safety Monitor

AS-interface是一种用于连接二进制传感器和执行器、工作在自动化体系最底层的网络系统。由于容易使用、操作可靠、应用量大等特点,也可用于机械安全领域。安全AS-interface系统可达到EN954-1规定的四级安全应用,并且可将标准部件和安全部件混合使用。

The actuator-sensor interface （AS-interface） has established itself as a system for networking primarily binary sensors and actuators at the lowest level of the automation hierarchy. The high number of installed systems, the ease of use and the reliable operating behaviour also make the AS-interface interesting in the area of machine safety. The safe AS-interface system is intended for safety applications up to Category 4 in accordance with EN 954-1. Mixed operation of standard components and safe components is possible.
